Příspěvek k hodnocení bezkontaktních metod měření složitých geometrických tvarů vyrobených aditivní technologií

Abstract

The topic of the dissertation is a contribution to the evaluation of non-contact methods of measuring complex geometric shapes produced by additive technology. 23 samples divided into two types were used for experimental research:

Type A – 13 pcs are samples with a full radius arch with the use of supports in the arch. Type B – 10 pcs are samples with a defined radius without the use of production supports.

All samples were produced with 6 different print parameters. The variable data were the parameters: laser power and speed of the application bar. The SLM method and the material of corrosion-resistant steel AISI 316L (1.4404) were chosen. Experimental samples were made for metrological tasks and their geometric accuracy.

The main goal is to compare the possibility of scanning a set of points for later evaluation of geometric tolerances and structural elements on two types of experimental samples with two optical measuring devices. Part of the evaluation is the determination of the most suitable printing production parameter for the creation of angular planes.

The dissertation is divided into several chapters, from the introductory text of the work to the determination of the goals of experimental activity and research, theoretical elaboration of the research of the given issue. The penultimate chapter is an evaluation of the research activity, where the areas of measuring angular planes are comprehensively included with a comparison of the nominal CAD model depending on the creation of production supports and their influence on geometric accuracy. The output is the achieved results and benefits of experimental activity for the field of Engineering Metrology and Additive Technology.

The results and their benefits will be further published and expanded with new experimental activities associated with the geometric precision of additive technology.
